I have decided to try to help you, Ellpus, because I am very interested to see those goat pictures.
You have to upload your pictures to someplace on the net and then link to them.
This link is where a lot of people on A2K post pics.

Use the above link to go to the Raven's Realm. Start a new album. Follow the instructions they have and upload your pic from your computer. Once you have your picture up, right click on it, hit "properties" and then copy the information from there. If you are on a Mac, this last step is slightly different. Let me know if you are and I'll walk you through it.
Now, come back to A2K and start posting a message. Hit the "preview" button. In the preview window of A2K, there is a button for images. Click it. Paste the information that you copied earlier.
And there you have it. Let me know if you have any problems, and I'll be glad to "ellp" you out.
